Tyler Swantek, 24, was already in custody on drug charges when police tacked on a first-degree murder charge.

Police said he killed his father, Todd Swantek, and left the corpse on the couch for weeks. The Standard-Speaker reported that Swantek allegedly shot his father in the head with a rifle.

Police reportedly were called to the scene in Frackville, Pennsylvania, in late May by a friend of Todd Swantek's, who had not heard from the father for a month. When police entered the house, they found a gruesome scene: The badly decomposed body was on the couch, covered in blankets and a sleeping bag, the Standard-Speaker reported. Police said they searched the house and found the rifle, which they believe to be the murder weapon, in Tyler Swantek's bedroom.

There were a number of candles and air fresheners in the house, apparently put out in an attempt to mask the smell, the Standard-Speaker reported. Police said that when they interviewed Tyler Swantek about his father's death, he showed no emotion. An autopsy report suggested that the body may have been on the couch for months before it was discovered. Swantek appeared in court where he asked for reduced bail for drug charges, but the judge didn't agree to the deal. The judge reportedly said, "He's a danger to himself and society."
